3.24 Reactor Coolant Inventory Trending System (RCITS)
Apolicability Applies to the operability requirements for the Reactor Coolant Inventory Trending System (RCITS) when the reactor is critical.
Ob.iectives lo assure operability of RCITS instrumentation which may be useful ir.
diagnosing situations which could repre:ent or lead to inadequate core cooling.
.Soeci fication 3.24.1 Reactor Coolant Inventory Trending System (RCITS)
(a) One channel of the two channels shall be OPERABLE.
A channel is 3
composed of a hot leg level and a RV head level.
With no channels OPERABLE, operation may continue and immediately initiate corrective action to return at least one channel to OPERABLE status as soon as possible.
If at least one channel is not restored within 30 days, details shall be provided in the Monthly Operating Report.
These details shall include cause, action being taken and projected date for return to OPERABLE status.
(b) One void fraction channel in each Reactor Coolant loop shall be OPERABLE. With no channels OPERABLE, operation may continue and immediately initiate corrective action to return at least one channel to OPERABLE status as soon as possible, if at least one channel is not restored within 'O days, details shall be provided in the Monthly Operating Report.
These details shall include cause, action being taken and projected date for return to OPERABLE status.
Bases The RCS Inventory Trending System (RCITS) (Reference 1) provides indication of the trend in wat.
inventory in the hct legs and reactor vessel during the approach to inadequate core cooling (ICC).
In this manner RCITS provides additional information to the operator to diagnose the approach of ICC and to assess the adequacy of responses taken to restore core cooling.
o 3-128 Amendment No.
